A crate is pulled to the right with a force of 71.6 N, to the left with a force of 228.2 N, upward with a force of 457.7 N, and downward with a force of 232 N.

Pt 1: What is the net external force in the x direction? Answer in units of N.
Pt 2: What is the net external force in the y direction? Answer in units of N.
Pt 3: What is the magnitude of the net external force on the crate?
Pt 4: What is the direction of the net external force on the crate (as an angle between −180◦ and 180◦, measured from the positive x-axis with counterclockwise positive)?
